ESP32-C3 BLE Garage Door Kit with ESP32 + Relay
ESP32-C3 BLE Garage Door Kit – Open Your Garage by Just Walking Up, No Button Needed
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Picture this: you roll up to your garage on a scooter or cycle, hands full, and the door swings open automatically. No remote, no keypad—just your phone’s BLE signal. This kit turns that into reality with the tiny yet powerful ESP32-C3 Super Mini, a relay, and a few supporting parts. In a single afternoon build, you’ll have a system that opens the garage when it detects your paired phone nearby and closes it safely after 30 seconds.
What You'll Build
A compact, self-contained automatic garage door controller. The ESP32-C3 scans for your phone’s Bluetooth Low Energy presence. Once detected, the relay pulses to open the door. A reed switch confirms the door position, and after a 30-second timer, the relay closes the door again. The whole circuit fits inside the included ABS enclosure, ready for mounting beside your existing garage door opener.
What You'll Learn
- BLE advertisement scanning and proximity detection on the ESP32-C3
- Driving a 5V relay from a 3.3V microcontroller using a protection diode
- Reading a magnetic reed switch to confirm door open/close state
- Basic soldering and PCB prototyping for permanent installations

Who This Kit Is For
Young makers aged 10–15 who want to move beyond blinking LEDs and build something that solves a real home problem. It’s perfect for ATL Tinkering Lab projects, CBSE Class 8–10 science fair demonstrations, or a first IoT automation build. Even B.Tech ECE/EEE students use this kit as a quick prototyping base for Smart India Hackathon ideas involving BLE proximity and appliance control.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion, which walks through every connection and line of code. If something still doesn’t work, message us on WhatsApp for direct help from our team.
Can I use this with an iPhone or only Android?
The kit works with any Bluetooth Low Energy phone, including all modern iPhones and Android devices. The detection is based on BLE advertisements, which both platforms broadcast when your phone is nearby.
Will this interfere with my existing garage door opener?
No. The relay output connects in parallel with your wall switch or remote terminals. You can still use your manual button or remote as before. Our guide includes clear wiring diagrams for common garage door opener models in India.
Is soldering safe for a 10-year-old?
The soldering iron included is low-wattage and safe with adult supervision. We recommend a guardian oversee the soldering steps. The prototype board uses large pads, and the AI companion includes a beginner-friendly soldering tutorial.
ESP32-C3 relay opens garage door when own phone BLE detected nearby. Auto-close after 30 seconds.
